GAS-REGULATING MEANS.

Specification of letters Patent.

Patented July 29, 1913.

To all whom it may concern:

Be it knownthat I, EDWARD J. GOLDBLATT, a citizen of the United States,and resident of Chicago, in the county of Cook and State of Illinois,have invented new and useful Improvements in Gas-Regulating Means, ofwhich the following is a description, reference being had to theaccompanying drawings, which form a part of my specification.

My invention relates more especially to means whereby theflow of gasfrom its source ofosupply to the point of consumption may be controlled;the invention being more especially adapted for use on vehicles, such asautomobiles, and the like, where the gas for use in the various lamps ofthe vehicle is contained in a tank orreceptacle under pressure, whichtanks or receptacles are from time to time replaced by newly chargedreceptacles, which are mounted in' acertain manner on the vehicle andgenerally at a point beyond the reach of the operator while in theautomobile or vehicle. W v f The object of my invention is to providemeans whereby the flow of gas from the tank or receptacle may becontrolled by the operato,r while seated in the automobile or vehicleafter the tank has been connectedup and the valve in the tank itself hasbeen opened to permit the flow of gas into the passages or conduits ofmy improved device.

A further object of the'invention is to provide means whereby apredetermined pressure of gas at the point of combustion may bemaintained after the flow has been regulated, at the same timepermitting the operator to shut off the .flow of gas to the lamps andagain open the passages and obtain the flow at the previously determinedpressure, without the necessity of stopping the automobile or vehicle tolook 'at the burners of the lamps supplied from said device; the meansbeing especially adapted for use where mechanism is provided forelectrically igniting the lamps while the operator is seated inthevehicle.

Other advantages inherentin the device Will be apparent from thefollowing descr pprovided with my improvedregulating device.

device. Fig. 3 1s a diagrammatic view -0 my 1m- Fig. 2 is a similar viewillustrating a, modified manner of attaching m conveying the gas to theburners; the view illustrating the different parts in perspective, andshowing the various elements whereby the gas may be conveyed from thetank to the burners and electrically ignited from a point in the vehiclewithin reach of the operator. Fig. 4 is a vertical sectional view of theregulating device. Fig. 5 is a plan view of the operating key ormechanlsm. n a

In the exemplification of my invention, as illustrated in Fig. 4, thegas controlling and regulating means comprise a casing or member A,which is provided with suitable passages for the gas from the inlet endthereof, past the various valves, to the point of discharge orconnection with the conduit leading to the lamps; for example, the inletend of the member or casing A is preferably pro-. vided withthe nozzleor member 6 which as shown may be secured to the casing A by screwthreads; the nozzle 6 being provided with a tapered upper end which isadapted to fit into the discharge end of the supply tank B, see Fig. 1,or a suitable connection, see Fig. 2; the discharge end of the tankbeing usually provided with a flaring orifice into which the nozzle ormember 6 may extend. The discharge end of the tank is externally screwthreaded, and in order to pro- .Vide a tight joint or union, I providethe nozzle 6 with the'annular shoulder 7 which is engaged byunion nut 8.It is apparent from this construction, that by screwing nut 8 onto theexternally threaded discharge end of the tank, a tight union will beeffected between member A and the tank B. I

The nozzle 6 has a central port or passage 9 which registers with thevertically extendproved mechanism showing a manner of ing bore orpassage 10 in the member A, and

this passage 10 communicates with the longitudinally ext nding passage11. The passage 11 is preferably made to extend from one end of member-A to a point where it connects with the vertically extending passage12, which leads upwardly through the stem 13, which forms a guide forthe needle valve 14. The lower end of valve 14 is slightly reduced so asto provide a chamber at the point 15, immediately above the seat of thevalve- Communicating with chamber 15 at a point above the connectionbetween passage 12 and passage 11, is a passage 16, extending preferablyat an angle to the preceding passages as clearly shown in Fig. 4.

reduced so as to provlde the chamber 22,

bottom of member A to a point above the seat of needle vah e 14, and isintersected by a passage 17 which has an upward extending portion 18,which provides a. seat. for the needle valve 19. This needle valve 19extends through the vertically extending passage 20 in the upwardlyextending stem 21 which forms a guide for the valve. The lower end ofneedle valve 19 is also slightly above the seat of the valve, whichcommunicates with the longitudinally extending passage 23, extendingthrough the discharge endof member A.

The discharge end of member A is preferably externally threaded as shownin Fig. 4 and provided with the flared orifice 24 which is adapted toreceive the oppositely beveled end of member 25, to which is connectedthe conduit 26 which conveys the gas to the lamps or place ofconsumption. In the construction illustrated, the discharge end 25 isshown provided with an annular shoulder 27, which is engaged by theunion nut 28, which nut is adapted to screw onto the externally threadeddischarge end of member A, as shown, whereby a tight union or connectionwill be effected between the beveled surfaces mentioned.

As the various passages are preferably bored in member or casing A, andin order to permit'their bein readily cleaned, they are formed in thedifferent directions, but in direct or straightlines, shown in Fig. 4,

with the outer ends of the passages 11, 16,-

17, provided with the screw plugs 29, 30, 31. It is apparent from theconstruction shown, that by removing the plugs 29, 30, 31, removing theneedle valves 14 and 19, and by detaching member A from the gas tank andfrom the conveying conduit through the unscrewing of union'nuts 8 and28, that the passages will be readily accessible, permitting them to bethoroughly cleaned, should occasion require: the passages being soformed that they may be readily drained.

The stem 13 of member A is provided with internal screw threads whichmesh with threads provided on the lower part of the stem of needle valve14, as clearly shown in Fig. 4, in order to control the position of thevalve. Thenpper outer end of stem 13 is preferably screw threaded asshown, so as to receive the nut 32 whereby the packing 33, whichsurrounds the stem of needle valve 1.4, is firmly held in place, therebyproviding a tight joint to prevent any flow of gas along the stem. Theupper surface of stein 13 is preferably beveled in the manner shown inFig. 4, so that when nut 32 -is screwed down onto stem 13, the packing33 will be forced. down onto the beveled surface of the stem and firmlyagainst the .stem of needle valve 14.

The upper end of the stem of needle valve 14 is preferably made angularin cross section so as to fit a squared or angular opening 34 providedin the shank or stem of the key 34, see Fig. 5. The upper part of thestem of valve 14 is provided with a sleeve 35 to the lower end whereofis secured a pinion 36 which meshes with a pinion 37 secured to theupper end of the stem of needle valve 19. This valve 19 screws into thestem portion 21 of member A, similar in manner to the valve 14, aspreviously described, and this valve is also made gas tight by thepacking 38 which is maintained in place and controlled by the nut 39which screws onto the stem portion 21. Pinion 37'is preferably securedto the upper end of valve 19 by a key 40; and the upper end of the valvestem 19 is preferably made to extend slightly beyond the pinion 37 andis formed angular in cross section so as to adapt it to a suitable keywhereby the valve 19 may be operated, should the key34 'be misplaced.

In order to prevent sleeve 35 and its pinion 36 being withdrawn from theupper part of the stem of valve 14, I secure an annular plate ormember-41 to the bottom of pinion 36, by means of the screw 42, orotherwise.

As shown, the plate 41 is of greater diameter than pinion 36 andoverlaps pinion 37 (which is securely fastened on the stem of valve 19)thereby preventing the withdrawal of the sleeve 35 and pinion 36. I alsoprefer to provide a washer 43 interm diate of pinion 36 or its plate 41,and the upper part of nut 32.

The operating key 34 is preferably shown in the nature of a disk, seeFig. 5, provided with a central shank or hub portion which is providedwith an enlarged opening to receive the upper end of sleeve 35; whichgives it bearing; the central part of the opening is extended andangular in cross section as previously described, forming the opening 34which receives the upper squareend of the stem of valve 14. If desired,the key 34 may be held in place on stem of valve 14, by the thumb or setscrew 44. The upper side of this key 34 is provided with opening 45, ofinverted L-shape in cross section. This opening 45 corresponds to theshape of the upper end of sleeve 35, which is provided with the cutawayportion 46 adapted to receive the extended portion 47 of the key. It isthus apparent from the description that the key 34 is intended tooperate valves 14 and 19 separately, by being adapted to fit the stem ofvalve 14 when in one position.

tion will induce the pinions to be rotated.

The valve 19 is then turned-so as to provide sufficient or the desiredpressure at the tit) burners of the lamps, thus regulating the flame,which is accomplished by the operator before seating himself in thevehicle. Having determined the pressure, in order to give the desiredsize of flame, key 34 is then withdrawn from its inverted position andplaced in the position shown in Fig. 4, namely, out of operativerelation with'sleeve 85, By placing the key 34 in the position shown inFig. 4, it is put into operative relation with the stem of valve 14,which may be con-' sidered the controlling valve. It is evident thatafter the pressure or flow of gas has been determined by the regulatingvalve 19, the flow of gas to the burners may be controlled or shutoff bythe operator in the vehicle through the operation 'of controlling valve14; and when it is again desired to ignite the lamps, the operator needonly open valve 14, without leaving his position in the vehicle, as thesetting of valve 19 will give the predetermined flow or pressure.

As previously stated my improvement is especially intended for use inconnection with automobiles wherein the burners are to be electricallyignitetd. For example, in 3, I illustrate, diagrammatically, one methodof employing my invent-ion, wherein the member or valve casing A isshown connected to a conduit 26, which may extend beneath the body orvehicle and lead forward to a point in proximity to the lamps, Where theconduit 26 n is shown. provided with suitable flexible connections 26which supply the gas to the burners 49, 49. These burners 49 are shownprovided with suitableelectrodes 50 and 51, one of which isconnected toa terminal 52, which leads to a contact point of a suitable electricswitch C, which switch is shown mounted on a spark plug D of one of thecylinders of an engine; the switch being, of course, insulated from thespark plug; and the switch is electrically connected through the lead 53with the mag.- neto E; the switch C being operated from the seat of theoperator by means of the springcontrolled mechanism'F, through themedium of the cord 54.

In Fig. 1, I illustrate my improved regulating means ,locatedimmediately adjacentto the gas tank-or receptacle B and to the outsideof the body of the vehicle; the upwardly ext-ending concentric stem ofvalve 14 and. the sleeve 35 being held in proper position by a bracket Gof any suitable construct-ion; thus enabling the means to be controlledor operated from the seat of the operator.

In Fig. 2, I show a modified manner of securlng the means in place,whereby the operating stems are brought up through the floor of thevehicle and at the same time within reach of the operator. In thisconstruction, an intermediate connection or pipe 55 is provided, one endof which is connected to the outlet end of tank B while the other end isconnected to the inlet end of member A by means of a suitable union nutas at 8. By employing the style of gas tanks at present more generallyused, it is necessary to have the same mounted in a horizontal positionin order to obtain the proper flow of'gas.

My construction shown and. described is especially adapted for use inconnection with the style of gas tanks referred to, and as shown inFigs. 1 and 2, permitting the tanks to be mounted as previously statedso as to secure the proper flow of gas.

From the construction shown and described, it will be seen that but onekey or operating member is necessary; and when the key or member 34 isremoved by the operator neither valve can be tampered with.

I have shown and described what I be- ,lieve to be the simplest and bestform of my invention, but the same may be altered in certain details,and the location and connection thereof to the gas tank or reservoir maybe modified without departing, however, from the spirit of my invention,and I do not wish to be understood, therefore, as limiting myself to theexact constructions shownand described, but
